A variety of hexacyclene derivatives with aliphatic substituents have been prepared and characterized via X-ray diffraction, calorimetry, thermogravimetric analysis, and computer simulations. A subset of these compounds are seen to display a liquid crystalline mesophase, while others transform directly from the crystalline to the isotropic liquid phase. The merits of tubular and smectic liquid crystalline models for the mesophase structure are discussed.
